IMPROVED HAMMER-HEAD.

TO ALLV WHOM IT MAY CONCE'RN:

Be it known that I, ROBERT BLACK, of Holyoke, Hampden county, Commonwealth of Massachusetts, have invented a. new und useful improved Hammer-Head; and 1 do hereby declare that the following is a full and exact description thereof, reference beingi hud to the accompanying drawings, und to letters of reference marked thereon. In the druwings- Figure 1 represents :t side view of my invention.

Figure 2 represents the parts separated.-

rI`his invention consists in a peculiar and advantageous method of manufacturing the'heads of hammers, so as to cheepon their construction, without' interfering with the eicncy or finish of the tool, it being of the ordinary shape outwardly, but formed in :L different manner.

In construction I form my hummerhe'.id of two parts, A end B, the one, A, having the tace und claw upon it, and formed with the eye C through it, und the other part being un eye or cose for the insertion ofthe handle. Usually these parts are formediin one piece, wrought from soft metal and then hardened and tempered. In this mode of construction greet diiiculty is found in forming the socket B upon the head, und a greet deal of labor has to be expended upon this part. In order to ohviete'this expenditure of time I form the socket B of a malleable iron, the remainder of-the head being formed iu the usual manner by forging, except .that the eye C is formed so as to receive the upper part a of the socket B. This socket, B, is then attached to the head by brazing'the former on to the letter.

By this means I obtain e hummer-heud quite its neet in appearance and fully oqunl in point of durability to those made on the old plain, with un expenditure of not more thun one-half of the time and lubor formerly used in their manufacture.

Now, having described my invention, what I claim es new, und desire to secure by Letters Patent, is-

As :t new article of manufacture, a. hammer-heed constructed of the parts A :1nd B, the part B being cast und attached to the purt A, substantially in the manner undfor the purpose described.

ROBERT BLACK.
